The answer is "dinosaur hearts" because hearts are soft body parts and do not fossilize well.
Scientists date and categorize fossils to determine when the organisms lived relative to each other. The resulting fossil record tells the story of the past and shows the evolution of forms over millions of years. Fossils are found in rocks and can be formed from hard parts of organisms, such as bones and shells, but soft parts do not form fossils well and fossils of body parts like feathers are much more rare.
One pattern in the fossil record is the presence of forms with transitional characteristics, arranged in sequential stratigraphic order. This means that the fossil record provides evidence for evolution and it shows tiny changes in the structures of organisms as time moved forward.
Major extinction events and natural disasters such as drought or volcanic eruptions can also be seen in the fossil record. Notably the fossil record has large amounts of iridium in the layer titled The 'K–T Boundary' or 'end Cretaceous event', which marks the extinction of the dinosaurs on land. Scientists believe this extinction was the result of a large meteor striking Earth.

The answer is "There was a body of water there at one point." Due to continental drift and changes to Earth's geography over time, oceans and lakes are in different places today than they were many millions of years ago.

Why do tectonic plates on the Earth's crust move?
Why do tectonic plates on the Earth's crust move?
Tap to see back →
Earth’s crust, also called the Lithosphere, is divided into tectonic plates. These plates move at plate boundaries due to the liquid hot mantle beneath the crust. Plates interact at three types of plate boundaries: divergent, convergent and transform. Most of the Earth's geologic activity takes place at plate boundaries.
Divergent: extensional; the plates move apart. Spreading ridges, basin-range.
Convergent: compressional; plates move toward each other.
Transform: shearing; plates slide past each other. Strike-slip motion.
At a divergent boundary, volcanic activity produces a mid ocean ridge and small earthquakes. Convergent boundaries create mountains, and transform boundaries cause earthquakes as well.

Earth’s crust, also called the Lithosphere, is divided into tectonic plates. These plates move at plate boundaries due to the liquid hot mantle beneath the crust.Plates interact at three types of plate boundaries: divergent, convergent and transform. Most of the Earth's geologic activity takes place at plate boundaries.
Divergent: extensional; the plates move apart. Spreading ridges, basin-range.
Convergent: compressional; plates move toward each other.
Transform: shearing; plates slide past each other. Strike-slip motion.
At a divergent boundary, volcanic activity produces a mid ocean ridge and small earthquakes. Convergent boundaries create mountains, and transform boundaries cause earthquakes as well.

At the Mid-Atlantic Ridge, as the tectonic plates move apart, rock is pulled up from depth at the spreading axis and melts as it depressurizes. The molten rock rises to the seafloor and cools to form the layer of crust that paves the ocean floor. This is called "seafloor spreading" and is pictured below.

Convergent: compressional; plates move toward each other.
Transform: shearing; plates slide past each other. Strike-slip motion.
At a divergent boundary, volcanic activity produces a mid ocean ridge and small earthquakes. Convergent boundaries create mountains, and transform boundaries cause earthquakes as well.
The answer is "a divergent boundary."
Earth’s crust, also called the Lithosphere, is divided into tectonic plates. These plates move at plate boundaries due to the liquid hot mantle beneath the crust.
Plates interact at three types of plate boundaries: divergent, convergent and transform. Most of the Earth's geologic activity takes place at plate boundaries.
Divergent: extensional; the plates move apart. Spreading ridges, basin-range.
Convergent: compressional; plates move toward each other.
Transform: shearing; plates slide past each other. Strike-slip motion.
